Hi All! I thought that the drive system was making a bit more noise than I expected so I secured the belt drive cover aside and ran up the rpms in neutral to check for bearing noise, etc. There wasn't any noise but I did notice that the primary sheave did not close as far as I expected, the belt only came within ~3/4" from the top of the sheave. See video link below (I was unable to upload it directly). I ran the RPMs up 5,000 (manual indicates that this is max for this engine). Is this expected behavior or should I remove the primary sheave and check roller diameters, clean & re-grease everything? I will be traveling with newer machines so want to be sure that I can travel as fast as this machine is capable. 🙂 Thanks in advance! https://www.dropbox.com/scl/fi/qof63w1kohal8wzmikfpt/IMG_0234.MOV?rlkey=j4h8ejm0ogjvlluyy5olagvrn&dl=0

Hello All! I heard a dripping noise after checking my drive belt for bearing noise (see other post). I was able to determine that it was coming from a protrusion under the passenger side of the engine - see attached video. Any idea what this is and what is likely required to repair it? Thanks in advance! IMG-0235.MOV

Wasn't sure exactly how to title this thread as I have a few issues with my newly acquired hisun UTV. Hopefully going to consolidate all the issues in one thread. I purchased from a guy who had rebuilt the engine replaced the fuel pump as well as re-done the front end. He had the unit running and driving when it quit and would not start. He got frustrated and decided no more projects and sold it to me. Unit is in excellent condition physically.....hardly any scratches on the plastics. All in all its a good unit with the following issues/symptoms 1) Mis fire and stalling out when revved Well as you can see by the title of the first issue I managed to get the unit running. Seems that the battery was very weak. I charged the unit and it fired up fine. The engine seems to stutter and misfire when revved and once the unit warms up it stalls out. I think it's a fuel issue as if I give it a shot of ether it starts back up. Additional Note: Revving engine in Neutral seems to cause indication to flicker and occasionally the reverse light comes on which seems to kick in the reverse rev limiter. Have also hade this happen when driving around. Reverse Light flickers and revs get cut. 2) Fuel line configuration. When he replaced the fuel pump he got creative with the tubing and removed the "small fuel tank" (See pictures) Not sure what the purpose of this tank is but would love some pictures of a stock set up so I can put everything back together correct. 3) Issues engaging in gear The unit seems to have issues going in to gear...I will move the shifter in place but the gear won't engage and the lights don't indicate correct. It takes a few tries to engage and sometimes it grinds a bit 4) Rack and pinion slipping This problem is probably a simple replacement fix...when turning to the right with the vehicle not moving the steering just slipps and turns without turning the tire. I believe I just need to replace the rack and pinion but if there is something else please let me know. Any insight or tips on resolving any of these issues would be much appreciated.

I recently bought a 2010 Hisun 700 UTV and have been having a heck of a time with the throttle cable and carb. I did get it to 38 miles an hour, but now its dropped to 33. Is that the full speed for this buggy? I am on my second throttle cable trying to find the correct length to make the speed consistent. I floor it, but it takes a good while to get up to speed. What is everyone else getting for speed? And any ideas on how to set the throttle cable or adjust the carb? Thank you!!

How to adjust linkage on 700 hisun 700 Tran. Linkage

I have a hisun 700 that was running and driving good but a while ago it just stopped moving. It was acting like it was in neutral but would shift through all the gears. I pulled the engine and put a new wet clutch in and then it was driving again. After about 20 minutes is stopped moving while I was driving. So I pulled off the outside clutches and moved the transmission shaft while in gear and it just would spin nothing happened. I decided to pull the engine again and something with the movement of me pulling the engine must have did something cause now spinning the shaft would spin the drive shaft. I split the engine apart to get at the transmission and I can’t find anything broke or anything there is some metal shavings but can’t find where they are from. Does anyone have any ideas?

Help please! Had problems with my Hisun 700 not wanting to start. Found that the fuel pump was not working. After doing some checking on the wiring to the fuel pump found that the ground was not working. Spliced a ground wire into the wiring harness and attached to the frame BAM fuel pump worked. UTV started and runs great. Since then have found that the 4x4 and rear differential lock is not working. Could all this be a problem with the relay panel or possible computer (or whatever it is called)? Relays are all saudered in so the whole panel will need to be replaced if so. I'm really stumped and don't want to replace more than what is needed. Thank you for any information

Bike was flooded in tropical storm. Replaced ecu and coil. Motor turns over but no spark have 12volts on one wire of coil. How much voltage should be on other small wire? Crank position sensor is about 200ohms. . Cleaned plug with sandpaper. Want a wiring diagram to check voltage at ecu. I have update. The blue wire going to coil has no voltage when turning it over. The white with black stripe has 12vdc when key is turned to on position.also, how do I clean the connectors on ecu? I dont see how I can get a screwdriver in there to release them. Found a schematic.i still need to clean connectors though

my name is albert i have in my shop a hs700utv that im getting no fire to coil i replaced the cdi and checked the relays and ignition switch out getting power to the cdi but nothing to coil and i didn't find any broken wires. they said that it was running fine and then it just stopped and wasn't getting any power to the coil is their another sensor on here that will stop it from firing i have looked at a wiring diagram but im not seeing anything different from what i know i checked the cdi and im getting fire to it but not to coil and this is a second coil no difference and also this is a delphi cdi 2 port is their any way to check it i know im getting power to the black plug in cdi on the # 10 the green and black wire but nothing else the blue and black wire is opposite of it the emergency brake and neutral switch is working is their a obd II plug for this i found one in back of pickup bed but i cant find a scanner but im not sure if it is one and im getting power to the stator the threee wires im at a lost here

Good morning. I have a 2008 HiSun 700 Atv that my buddy rode with no water in it and the motor is fried. I am a retired mechanic and need to know where can I get a motor used or new one. I heard that a Yamaha 700 might work? Anybody know.

How can i Disconnect Hisun 700 2017 UTV 40 km/h speed limiter ? Preferably with a switch.

So i have a 2011 EFI 700. the SxS will crank right up everytime without any issues. If i let it run or ride it for about 10 mins it will shut off and then it may turn on if i am lucky but most time i have to let it sit for like 3 hours and then it will run again. i have done the following -New fuel filter -New injector -New spark plug -New coil pack and plug wire -New air filter Also could i get a grizzly 660 engine and put in it or would it not work.

Hi friends. I'm Anıl. I live in Turkey. I have a Hisun 700 UTV 2015 Models. My problem is : inability to change gear after the engine has started. Before the engine starts, it can shift into all gears; but after running, I cannot change gear. At about 3000 km. Fuel injection model. Can anyone help on this topic? Thank you!

When I try to back up a hill, belt squeals and engine surges. Will not back up. Never have any problem going forward on the steepest hills. Have seen this problem posted before but, never an answer.

2009 Hisun 700.... previous owner did a number of changes. This part is under the driver's seat but not attached to anything. Is this the old fuel pump?

We bought a Hisun 700 UTV, used. It has an issue when you run it in high. It drives but acts like it is shifting when you get around 35mph. Clutch looks good. Read many articles and not sure transmission or something in rear of UTV. Looking for any advice.

I have a hisun 700 I went out to start it one morning and it made a clunk then nothing I am mechanical inclined so I start trying to figure things out. I narrowed it down to starter. I changed it out with a brand new starter it made a grinding sound then nothing please advise me as I’m a old points and spark plug kind of guy not much experience with utv point me in the right direction don’t want to start tearing things down that don’t help??

We just got a used Hisun utv which burns oil like crazy and needs a diff seal. I'm having a hard time finding parts so far so I was wondering whether two models were the same. Our model is Supermach 700U 2008. Many times the Hisun HS700 shows up when looking for parts. So are the parts between these two models the same? Are the essentially same with different stickers on it? Thanks Lucas

Hi, Don't know much about anything utv but I figured out my fuel pump wiring harness needed to be replaced. Installation looks pretty straightforward, plug into fuel pump and plug in the two pigtails. Question is: one of the Pigtails on the old harness I am replacing had a splice in the black wire and attached to a bolt on the engine. Is this necessary? Is the black wire, I'm assuming it's the ground, grounded at the other end of the pigtail?

2012 hisun 700 efi front runner turns over hard and the valves don't move and no compression any ideas on what could be wrong with it ???? Thanks in advance

Hi Everyone, This is my first post. I believe I have my starting issues narrowed down to decompression springs (good grounds, one way bearing, etc.) so I order them and now I have no idea how to install. I am handy enough, but looking for a video or other instructions on how to replace them. If this has been covered and I just can't find it, appreciate some input on where to go. If not, would appreciate some instruction! Haven't done this one before. Thanks.
